A STUDY OF PRIMARY NUTRIENT FORAMINA IN FEMUR
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 36
Abstract
BACKGROUND Nutrient foramina are seen in all long bones. They vary in number, size and their position on the surface of the bones. These foramina are significant, as nutrient arteries which are the main source of blood supply to long bones, pass through them to vascularise the bones. Of the primary and secondary nutrient foramina that are seen in bones, the main nutrient artery enters through the primary foramen. Data obtained from the study of parameters like number, site of entry, direction of nutrient foramina will be of immense value to surgeons, orthopaedicians and radiologists while performing various procedures. The aim of this study was to identify the number, type, location and direction of foramina and calculate the foraminal index. MATERIALS AND METHODS The descriptive study was done using 121 femora. The length of each bone and distance of the primary nutrient foramen from the upper end of the bone was measured using an osteometric board. The location of the foramina on the surface of the bone, direction of the nutrient canal and presence of secondary foramina were noted. The bones of the right and left sides were compared. RESULTS In most of the femora, there was a single primary nutrient foramen located on the posterior surface in the middle segment and directed proximally, whereas a few of the bones had no primary nutrient foramina and a few had two. CONCLUSION To facilitate a better outcome for all radiological and surgical procedures, clinicians must be aware of variations from the normal anatomy. The findings from this study will definitely aid them in this aspect. Stature of an individual can be measured from the position of primary nutrient foramen in forensic investigations.
